Aha! Wood! That I know how to talk about. Osage orange is a very nice wood to work with, it turns very nice and tends to be quite durable. Considering the colour on that handle, you have an older piece of it (Which looks better than bright yellow in my opinion.). What was the finish you used may I ask? As well as that what was the train of thought that led up to using micarta as pins? I've never seen that before. Nice patina by the way.
